sdk swift must identify swiftpm/BoundaryML/baml-swift

Error message

sdk swift must identify swiftpm/BoundaryML/baml-swift

What it means

The Swift SDK entry is pinned: it must declare registry "swiftpm" and package "BoundaryML/baml-swift". Any other values for language "swift" fail validation, keeping Swift releases tied to the official XCFramework repository.

Solutions

Set registry = "swiftpm" and package = "BoundaryML/baml-swift" for the swift entry
Check for typos in the org/repo slug, including case
Regenerate the manifest via the release tooling rather than manual edits

Example fix

// before
[sdk.swift]
registry = "github"
package = "boundaryml/baml-swift"

// after
[sdk.swift]
registry = "swiftpm"
package = "BoundaryML/baml-swift"

Defensive patterns

Strategy: validation

Validate before calling

fn swift_entry_valid(p: &SdkPackage) -> bool {
    p.registry == "swiftpm" && p.package == "BoundaryML/baml-swift"
}

Prevention

Copy the pinned swift entry from prior release manifests
Do not point the manifest at forks or mirrors
Match the org/repo slug exactly, including case

When it happens

Trigger: validate_sdk() sees language == "swift" with a registry other than "swiftpm" or a package other than "BoundaryML/baml-swift".

Common situations: Forking baml-swift and pointing the manifest at the fork; using a different casing or org name; copying an entry from another language.
